Glacier surge mechanism: 1982-1983 surge of variegated glacier, alaska.
نویسندگان
چکیده
The hundredfold speedup in glacier motion in a surge of the kind the kind that took place in Variegated Glacier in 1982-1983 is caused by the buildup of high water pressure in the basal passageway system, which is made possible by a fundamental and pervasive change in the geometry and water-transport characteristics of this system. The behavior of the glacier in surge has many remarkable features, which can provide clues to a detailed theory of the surging process. The surge mechanism is akin to a proposed mechanism of overthrust faulting.

Bering Glacier surge 2011: analysis of laser altimeter data
The Bering Glacier–Bagley Icefield system in Alaska is currently surging (2011). Large-scale elevation changes and small-scale elevation-change characteristics are investigated to understand surge progression, especially mass transport from the pre-surge reservoir area to the receiving area and propagation of the kinematic surge wave as manifested in heavy crevassing characteristic of rapid, br...
متن کاملWav Es of Accelerated Motion in a Glacier Approaching Surge: the Mini-surges of Variegated
Periods of dramatically accelerated motion, in which the flow velocity increases suddenly from about 55 cm/d to a peak of 1 00-300 cm/d and then decreases gradually over the course of a day, occurred repeatedly during June and July 1 978-8 1 in Variegated Glacier (Alaska), a surging-type glacier that surged in 1 982-83. These "mini-surges" appear to be related mechanistically to the main surge....
متن کاملThe 2015 Surge of Hispar Glacier in the Karakoram
The Karakoram mountain range is well known for its numerous surge-type glaciers of which several have recently surged or are still doing so. Analysis of multi-temporal satellite images and digital elevation models have revealed impressive details about the related changes (e.g., in glacier length, surface elevation and flow velocities) and considerably expanded the database of known surge-type ...
متن کاملMass Balance Evolution of Black Rapids Glacier, Alaska, 1980–2100, and Its Implications for Surge Recurrence
Surge-type Black Rapids Glacier, Alaska, has undergone strong retreat since it last surged in 1936–1937. To assess its evolution during the late Twentieth and Twenty-first centuries and determine potential implications for surge likelihood, we run a simplified glacier model over the periods 1980–2015 (hindcasting) and 2015–2100 (forecasting). The model is forced by daily temperature and precipi...
متن کاملGlacier Surge Mechanism Based on Linked Cavity Configuration of the Basal Water Conduit System
Based on observations of the 1982-1983 surge of Variegated Glacier, Alaska, a model of the surge mechanism is developed in terms of a transition from the normal tunnel configuration of the basal water conduit system to a linked cavity configuration that tends to restrict the flow of water, resulting in increased basal water pressures that cause rapid basal sliding. The linked cavity system cons...
